APPARATUS AND METHOD FOR MEASUREMENTING A IMPULSE OF THRUSTER

摘要

An impulse measuring device of a thruster and a method thereof are provided to increase the data processing speed and to precisely measure the very small size impulse by reducing the various errors. An impulse measuring device of a thruster comprises a swinging offer part(102), a sensor(105), and a data processing part(109). The thruster(101) is fixed at the swinging offer part. The thruster is reciprocated by the swinging offer part around the equilibrium point. The sensor measures the exercise hours of the thruster. The exercise hours of the thruster are the time to thruster pass through the arbitrary point-to-point interval. The amount of change of the exercise hours is the difference between the exercise hours while the thruster is running and the exercise hours while it is not.
